FRANK A CERRU'II, OF NEW YORKJN'. Y.

CREEPER OR ANTISLIPPIN'G DEVICE.

York, have invented certain new and useful Improvementsin Creepers or Antislipping Devices, of which the following is a specification.

This invention relates to creepers'or anti slipping devices which may be adapted to be applied to a boot or shoe or to the hoof of an animal, and it is the object of the invention to provide a creeper whichmay be quickly and readily applied andlocked in position and as readily removed, and to provide a device of this characterwhich is cheap in construction and efficient in operation. a

In the drawing accompanying and forming a part of this specification Figure 1 is a side *elevation of a creeper, showing an embodiment of my invention, applied to theheel of a'shoe.

Fig. 2 is an end elevation looking at the front of Fig. 1.

Fig. 3 is a plan view of the creeper.

Fig. 4 is a side elevation showing an embodiment of the invention as applied to the hoof of an animal; and

Fig. 5 is a sectional view of a modification.

Similar characters of reference designate like parts throughout the different views of the drawing.

The embodiment of invention shown in in Figs. 1 to 4 of the drawing comprises a plate 6 of a shape to conform to the heel of a shoe or hoof, said plate carrying downwardly projecting prongs 7 which may be stamped from the material of the plate 6 as shown. The plate has at the edge at one end an upstanding claw 8 shown as an integral part or bent up from the plate (3, said claw when the device is utilized as an anti-slipping device to be applied to the shoe being adapted to engage the back of the heel. Movably carried by the plate 6 o posite to the claw 8 is a claw 9 inlthe form of a plate pivotally connected at one end, as at 10, to the plate and having prongs at the opposite or upper edge to engage the front of the heel.

To fasten the plate to the heel a lever 11 is provided in the form of a bail to straddle the heel pivotally connected to ears 12 at Specification of Letters Patent.

Application filedOctober 25, 1916. SerialNo. 127,563.

opposite sides of the plate 6 and located between the clamping claws 8 and 9. 1 These ears, as shown, in said figures may be integral withand bent up fronrthe material of the plate.

Thebail or lever is connected to the movable claw 9 by links 13 pivotally connected at one end to cal-s14: integral with the claw 9 and the other endpivotally connected to the bail 11, as at 15.

'To fasten the creeper to a heel the bail 11 is thrown downward to assume the dotted line position shown inFig. 1 when the plate is adjusted to the heel to lie contiguous to the bottom thereof, when the bail is thrown upward lZO JSSIIIDB substantially the full line position shown in Fig. 1, this movement of the bail moving the clamping claw 9 forward and clamping the heel between said claw and the claw 8. lhepivotal connection of the links 13 with the bail relative to the pivotal connection of the latter to the ears 12 is such that when the claw 1 1 is in clamping position thepivotal' connection a of the links with the bail and claw 9 will be out of line with the pivotal connection of the bail with the ears 12, with the result that the links will exert a pull on the bail tending to draw the bail to the heel or the shoe adjacent the heel, the bail thereby serving to lock the clamping claw 9 in clamping position.

To release the clamping claw to remove the creeper it is only necessary to push or pull the bail downward so that it will assume the dotted line position shown in Fig. 1 thereby throwin: the clamping claw 9 away from the bee, as also shown in dotted lines. To facilitate the releasing of the bail it is formed with a fingerpiece 16.

In Fig. 4: I have shown the device applied to a hoof. The construction is the same as that shown in Figs. 1 to3, but in applying the device the clampin claw 8 placed at the front of the hoof while the movable claw 9 is at the rear of the hoof, the bail 11 extending over and embracing the front of the hoof.

The clamping claw 8 as well as the ears 12 may be adjustably carried by the plate 6 to adapt the device to different sizes of heels and also hoofs for which purpose said clamping claw and ears are constructed separate from the plate 6, as shown at 17 in Fig. 5 and carry a bolt or screw 18 to engage in slots 19 in the plate 6 and are secured in adjusted position by a nut 20 cooperating with the bolt or screw 18.

Having thus described my invention, I claim: p

1. A creeper comprising a plate having prongs and anupstanding claw at the edge; a claw pivotally carried'by the plate at' the edge opposite to the first claw to cooperate with the upstanding claw as a clamp; and

a bail pivotally connected to opposite sides of the plate between the claws and to which the pivoted claw is connected, said bail being operable to throw the pivotally supported claw into and out of clamping position and to lock said claw in clamping position. 2. A creeper comprising a plate provided with prongs; a clamping claw. at. one end of position.

3. A creeper comprising a prong carrying plate; an upstanding clamping claw at one end of said plate; a clamping claW pivotally connected to the plate at the end opposite to the first claw; ears at opposite sides of the plate between the clamping claws; a bail pivotally connected to the ears; and links pivotally connected at one end to the pivoted clamping claw and the other end pivotally connected to the bail, said bail being operable to throw the pivoted clamping claw into and out of clamping position; and the connection of the linkswith the bail'and clamping claw being so arranged that when the. bail is in position with the pivoted clamping claw in clamping position the pivotal connections of saidlinks will be off line with relation to the pivotal connection of the bail with the plate ears, substantially as and for the purpose specified.

4:. A creeper comprising a prong carrying plate; an upstanding clamping claw at one end of said plate; a clamping claw pivotally connected to the plate at the end opposite to the first claw; ears at opposite sides of the plate between the clamping claws; a bail pivotally connected to the ears; and links pivotally connected at one end to the pivoted clamping claw and the other end pivotally connected to .the bail, said bail being operable to throw the pivoted clamping claw into and out of clamping position.
